This invention relates to apparatus for making receptable bodies havingone end closed and the opposite end arranged with a ring having aninwardly extending shoulder for supporting a closure in said oppositeend of the receptacle bodies.

The apparatus is particularly adapted for forming a tubular receptaclebody from a flat blank ofipaper, inserting 'a metal ring having aclosure supporting flange in one end of the receptacle body, forming andinserting a flanged paper disk mthe opposite end of the receptacle bodyto constitute the bottom closure thereof, securing the bottom closure inthe receptacle body in two steps, and securing the closure supportingring in the receptacle body simultaneously with the final stepofsecuring the bottom closure in the receptacle body.

It is an object of the invention to adapt existing apparatus as shown inPatents No. 1,916,981, issued July 4, 1933, and No. 1,917,374, issuedJuly 11, 1933, to Ellis L. Jones, to secure a closure supporting ring inthe filling and pouring end of the receptacle. body formed in saidmachines.

It is another object of the invention to provide .a spinning head tosecure the closure supporting ring in the receptacle body adapted tohold the receptacle body against longitudinal movement in a holdertherefor during the final spinning of the bottom closure and thespinning of the closure supporting ring in the opposite ends of thereceptacle body.

It is a further object of the invention to provide. a spinning head forsecuring a closure supporting ring'in one end of a receptacle bodysimultaneously with the final spinning of a bottom closure in theopposite end of the receptacle body without interfering with said finalspinning of the bottom closure. 7

Another object of the invention is to operate both spinning heads fromthe same source of power.

Further objects and advantages of the invention will be disclosed in thedetailed description of the invention.

The embodiment of the invention is shown with an apparatus for makingpaper containers partly shown in Figures 1 and 2 as comprising a table 9supported in elevated position by legs partly shown at 10 in Figure 2. Atubular body I l is formed from a flat paper blank in the manner shownin the aforementioned Jones patentsand inserted in a holder 12 of aseries of tubular holders mounted on a conveyer in the form of a disk I3secured to a shaft 14 rotatably mountedin the table 9 and intermittentlyactuated by suitable means disclosed in the Jones patents to present theholders to different predetermined positions or stations.

Looking at Figure 1, the holder 12 at station A receives a receptaclebody I i from the body forming mechanism of the apparatus ,shown in theJones patents. The holders [2 and the receptacle bodies H are of suchsize and shape that the opposite end portions of the receptacle bodieswill extend from the corresponding ends of the holders, as shown at fand f in Figure 3.

During the positioning of a receptacle body H in a holder l2 at stationA, the end portion of the receptacle body is engaged with aclosuresupporting ring g positioned at the corresponding end of theholder by the lower end of a chute l5 having the upper end connected toa hopper (not shown) for a supply of said rings. The ring g. haslaterally extending flanges at the opposite ends, one flange extendinginwardly to support a closure member and the other flange extendingvoutwardly to engage the edge of the receptacle end portion and be curledor rolled with the y 3 receptacle end portion 1, as hereinafterdescribed.

At station B, a holder [2 presents the end portion 7 of the receptaclebody therein to means, indicated in a general way at l6, to form aperipherally flanged disk h from a web w shown in Figure 2, and insertsaid flanged disk in the receptacle body end portion f. The'mechanism I6is fully illustrated and described in the aforementioned Jones patents.The flanged disk h constitutes the bottom closure of the receptacle bodyH.

At station C, the flange of the bottom closure disk h is partiallysecured to the end portion 1 of the receptacle body by a primaryspinning mechanism indicated in a general way at l8 in Figure 1. Theprimary spinning mechanism 18 is of the same construction andarrangement of parts as the final spinning head for securing the bottomclosure disk h in the receptacle end portion I, and description of bothis not deemed necessary. The partial securing of the bottom closure diskis shown at i in Figure 3.

At the succeeding station D, the bottom closure disk h is finallysecured to the receptacle end. f simultaneously with the securing of theclosure supporting ring g to the receptacle body end portion f. Thesecuring of the bottom closure disk h to the receptacle body end portion1 is accomplished by a spinning mechanism comprising a series ofspinning rollers 19 rotatable carried in equidistantly spaced relationto each other by ahead 20 secured on one end of a shaft 2| rotatably andslidably mounted in a standard 22 supported by the table 9. The head 20is rotated from a suitable source of power shown as an electric motor 23supported by the table 9 and operatively connected to the shaft 2| by alongitudinally adjustable coupling comprising a head 24 secured to themotor shaft and having a series of openings therethrough for theslidable engagementof pins 25 fixed to and extended from a head 26secured to the end of the shaft2l opposite the. end secured to thespinning head 20, as shown in Figures 1 and 2. The coupling 24-.-26

permits the spinning head 20 and rollers l9 to be actuated intoengagement with the partially secured portion i of the flange of thebottom closuredisk h and the receptacle body end portion I to spin theportion 2' into a tight roll or bead,'as shown. at 7' in Figure 5, andto be actuated out of engagement with the bead 7. This longitudinaladjustment of the spinning rollers 19 and head 20 is accomplished by arock arm 21 secured at one end to a shaft 28 rotatably supported on thetable 9 the opposite end of the arm 21 being bifurcated and thebifurcation leg portions carrying rollers 29 to engage an annular groove30 in the shaft head 26, whereby the rocking of the shaft 28 will betransmitted to the spinning rollers I9 and head 20 through the arm 21and shaft 2| without interfering with the rotation of said spinningrollers and head by the motor 23. The shaft 28 is rocked by an arm 31secured at one end to the shaft 28 and having the opposite end connectedby a link 32, as shown in Figure 2, to the actuating means for theconveyer disk [3, as shown in Jones Patent No. 1,916,981, whereby thespinning rollers 19 and head 20 are actuated toward and away from theholder I2 at station D in synchronism with the intermittent actuation ofthe conveyer disk 13. The parts of the primary spinning mechanism l8 arethe same as the corresponding parts hereinbefore described of the finalspinning mechanism and are indicated by corresponding primed referencenumerals. Said spinning mechanism is reciprocated by the arm 3| throughan arm 33 secured at one end to the rock shaft 28' of said spinningmechanism I8 and the opposite end of the arm 33 connected to the arm 3|by an universal joint connection 34, as shownin Figure 1.

Simultaneouslywiththe final spinning operation of securing the bottomclosure disk 71. in the receptacle body end portion ,1, the closuresupporting ring g is secured in the receptacle body end portion f by aspinning mechanism actuated by and in coordination with the actuation ofthe final spinning mechanism l9-28. This spinning mechanism comprises anaxial support or spindle 35 slidably mounted in a bearing sleeve 36secured in the lower portion of a plate 31. One end of the support 35 isarranged with a head 38 to abut the outer face of the plate 31 and limitlongitudinal or axial movement of the support in a direction from' saidplate 31. The opposite end of the support 35 is provided with a head 39to engage in the closure supporting ring.

g and abut the closure supporting flange there: of to preventlongitudinal movement ofthe. receptacle body II in the holder [2, asfully de.-:. scribed hereinafter. The plate 31 is suspended from one endof a beam 40 supported at the op-. posite end portion by hollowstandards or spacers 4| and 42 secured to laterally extending earsof thebeam and the table and standard 22by rods.

and nuts screw threaded on the projecting ends of the rods, as shown at43, in Figures 1 and 2. The support 35 is keyed to the bearing 36, asshown at 45, to prevent the. support from rotating in said bearing butpermitting longitudinal movement of the support in the bearing limitedin one direction by the head 38. A tubular mem-, ber 46 having anintegral annular head or flange 41 at one end is mounted to rotate onand par.- ticipate in the longitudinal movement of. the support 35 byroller bearings. engaged in annular recesses in the opposite ends of thetubular. member 46, as shown at 48 in Figure 3. The end of the tubularmember 46 opposite the endhaving the. integral head 41.. is alsoprovided with an annular head or flange. 49 screw threaded in anenlarged bore portion at said end of the tubular member and having twoseries of equidistantly' spaced openings 50 and 51 for a purpose tcbehereinafter described.

The head 41 is arranged to carryequidistantly spaced rollers 52 to rollor spin together. the securing flange of the ring 9 and the end portionJ" of the receptacle body II. For this purpose, the head 41 is providedwith equidistantlyspaced recesses 53 extending inwardly from the outerperiphery of the head and radially of the head for the slidable mountingof carrier blocks 54. Each block has a headed shaft 55 fixed atthefreeend portion in said block with a projecting portion between theblock and shaft head rotatably supporting a roller 52. The blocks 54 andtheir associated rollers 52 are yieldingly urged outwardly from theouter periphery of the head 41 by springs 56 compressed between theblocks 54 and the bottom of the recesses 53.

This outward movement of the blocks 54 and associated rollers 52 iscontrolled by a hoodmember 51 having a conical or inwardly tapering face58 and a tubular portion 59 slidably mounted on the tubular member 46between the heads 41 and 49 of said tubular member. The conical face 58of the hood member 51 is engaged by rollers 50 carried in a bifurcatedouter end portion of the blocks 54 and forced against said conical face58;

by the springs '56., The rollers 52 are :mounted on theshafts 55 toextend in theplane of the head 39 andthe rollers 52 are adjusted towardand away, from the head 39 by sliding the hood member 51 on the tubularmember 46 to-position different portions of the'conical face 58relative,

to the rollers 60. The removable mounting-of the head 49 on the tubularmember 46 facilitates the mounting of the hood member on the tubularmember 46. V

Thissliding movement of the hood member is derived from and coordinatedwith the adjustment of the spinning rollers l9 and head 20 toward andaway from the partially rolled seam 2'. This operation is accomplishedby a bifurcated lever arm 6| having rollers 62 extendinginwardly towardeach other from the opposedfaces of the leg portions of said lever armto engage anannular groove 63 inthe tubular portion 59 of the hoodmember 51. The bifurcated lever arm 6| is secured to an intermediateportion of a shaft 64 rotatably supported at the end portionsindepending members 65 of a bracket 66 secured to the beam 46, as shownin Figure 6. The shaft 64 is rocked by and in synchronism with therocking of the shaft 28 of thetfinal spinning: mechanism l9,--28bya'rock arm '61 secured at the lower end portion to the shaft'28 andhaving at the upper end' portion amemn extending head 68 arranged withan arcuate slot 69 and ears 19 ex--v arm 61, as indicated at" in Figures2and 7,

and the upper end portion of the arm 1| is arranged with an opening'in'horizont'al alinement with the slot 69 for the engagement of abolt'in said slot and opening, said bolt having a head extending fromthe outer face of the arm head 69 in horizontal alinement with the earsand secured in the'arms by a nut engaged on the end portion extendingfrom the arm 1|, as indicated at 13 in Figures 1, 2 and '7. The upperend portion of arm 1| is adjustably and yieldingly connected to the arm61 to participate in the rocking movement of the arm 61 and compensatefor any undue resistance to the forward movement of the hood member 51and rollers 52 to prevent damage to saidparts. plished by a spring 14'compressed between one side of the head of bolt 13 and an abutment screwadjustably mounted in one of the ears 10 and a set screw 16 adjustablymounted in the other car 10' toabut the opposite side of the head ofbolt'13, whereby the arm 1| is adjusted to the desired angular positionrelative to the arm 61 by the adjustment of the screws 15 and1'6, andshould the forward "movement o'fv the rollers 52 and hood member 51toward the receptacle body end I meet with resistance, such as by anextra long receptacle body, the spring 14 will take up said resistanceand will shorten the actuatin stroke of the arm 1! without affecting theactuating stroke of the arm 61. The arm 1| is operatively connected tothe bifurcated lever arm 6| through a lever arm 11 secured at one end toan extending end portion of the shaft 64 and the opposite end portion ofthe lever arm 11 pivotally connected to one end of a link 18 having theopposite end pivotally and adjustably mounted in a slot an in the upperfree end of the arm 1|, as shown in Figures 2 and '1.

The rollers 52 and hood member 51 are simultaneously rotated about thesupport in syn- This is accomchronism with the rotation of the spinningrollers I9 and head 29 by operatively connecting the tubular member 46and hood member 51 to the shaft of motor 23. This-is accomplished by ashaft 8| rotatably supported in bearings 82 suspended from the beam 40and operatively con-, nected to the motor shaft by a gear 83 secured onthe motor shaft and meshing with a gear 84 secured to one end portion ofthe shaft Bl. The opposite end of the shaft 8| is operatively con:nected to the tubular member 46 and hood meme ber 51 by a'gear 85secured on the shaft, BI and,

able in the openings 50 in the tubular member.

flange 49 and the end portions slidable in corresponding openings in thetubular portion 59 of the hood member 51 and recesses 9! in the gear 81.p I

To facilitate the transmission of the longitudinal movement of the hoodmember to the tubular member 46 and support 35, the support 35andtubular member 46 are yieldingly urged away from the gear 81 by springs92 having an end portion engaged in a, recess 93 in the flange 41 of thetubular member 46 and the opposite end portions engaged in correspondingrecesses 94 in the gear, 81 and the intermediate portions of the springsextending through the openings 51 in the flange 49 of the tubular member46 and corresponding openings 95 in the tubular portion 59 of the hoodmember 51, as shown in Figure 3. As shown in Figure 6, there are threerods 89 and three springs 92 equidistantly disposed alternately of eachother. r V

In the operation of the spinnin mechanism at the station D position ofthe holders [2, the final spinning head I9, 29 and the ring retaininghead 39, rollers 52 and hood member 51 are actuated to the positionshownin Figure 3, during the rotation of the conveyer disk I3, by thearm 21 and lever arms BI, 61, whereby the spinning. head I9, 29 is movedto its rearmost position from the receptacleholder l2 and the hoodmember. 51 is also moved to its rearmost position from the receptacleholder which will move the head 39 androllers 52 in the same directionby the end of the tubular portion 59 abutting the head 49 of the tubularmember 46 beforethe hood member reaches its rearmost position andthereby moving the tubular member 46 and the rollers 52 carried by saidtubular member 46 and the support 35 which is connected to the tubularmember 46 by the ball bearings 48. The rearward movement of the support95, tubular member 46, rollers 52 and hood member 51 is stopped by thehead 49 abutting the gear 81, as shown in Figure 3. During the rearwardmovement of the hood member 51 prior to the abutment between the tubularportion 59 and tubular member head 49, the conical face 56 is actuatedto a position wherein the rollers 60 are engaging the portion of largestdiameter of said face whereby the rollers 52 are permitted to assumetheir expanded position under the force of the springs 56, as shown inFigures 3 and 4.

After the holder I2 is positioned between the head I9, 29 and hoodmember 51 are-moved to-' ward the positioned-holder I2, and during saidmovement, the head 39 will engage the closure supporting flange of thering g while the rollers 52. are still in their expanded position, asshown in Figure 4. The'forward' movement of the support 35 and itsassociated head 39 is caused by the springs 92 and is arrested by thehead 38 abutting the plate 31. Due to the position of the hood member 67at this point in its forward movement, the rollers 52 are still inexpanded position, as shown in Figure 4. The engagement of -the head 39with the ring 9 will firmly seat the ring in the receptacle body endportion f and firmly retain the receptacle body I l in the holder l2-against longitudinal displacement due to the present'use of the holderand receptacle of truncated shape; a I a L he continued forwardmovements of the spinning heads i9, 20 and hood member 57 will positionthe spinning head I9, 20 and the rollers 52 .intoengagement with thepartially formedrolI i and the receptacle engaging flange of the ring 9and the receptacle end I, whereby the final rolled seam 7' is formed andthe receptacle end portion ,f and receptacle engaging flange of the ringg are rolledtogether to secure the bottom disk It and the ring 9 in therespective end portions of the receptacle body, as shown in Figure 5. Inthe Figure 4 position of the spinning head for the ring g, the rollers=52 are positioned in'vertical alinem'ent with the receptacle engagingflange of the ring g asthe axial or longitudinal travel of the support35 and the tubular member 46 carrying the rollers 52 is in unison, andthe continued forwardmovement of the hood member 51 will position theportion of smallest diameter of the conical face 58 in engagement withthe rollers 60 so that the spinning rollers 52 are actuated to fullcontracted position into spinning engagement with the ring 5/ andreceptacle body end portion 9". 7

During the movements of the spinning heads 1-9, 20, the rollers 52 andhood member 51, said elements are continuously rotated, so that theengagement of the head I9, 20 and rollers 52 with the partially formedroll 2' and ring 9 will effect therol-l-ing' or crimping of said roll 2'and ring 9.

After the spinning operation has been completed retrograde movement isimparted to the spinning mechanisms, as shown in Figure 3, whereby theconveyer disk 13 is free to be actuated to move the holder I2 having acompleted receptacle 'body therein from station D.

- At station the completed receptacle body is eiec'tedfrom the holder l2by any suitable means, such as a blast of air delivered to the open endor thelreceptacle body by apipfili connected in communication to asource of air, such as acompressor, as showntin Jones Patent No;1,916,981.
